IBM Cloud Mobile Services - Server side Swift SDK for IBM Cloud Push Notifications Service

The IBM Cloud Push Notifications service provides a unified push service to send real-time notifications to mobile and web applications. The Swift server-side SDK for sending push notifications through the IBM Cloud Push Notifications services.

Ensure that you go through IBM Cloud Push Notifications service documentation before you start.

import PackageDescription
let package = Package(
    dependencies: [
        .package(url: "https://github.com/ibm-bluemix-mobile-services/bluemix-pushnotifications-swift-sdk.git", .upToNextMajor(from: "1.6.0"))
	]
)

sudo apt-get update // not required on Mac
swift build -Xcc -fblocks -Xlinker -rpath -Xlinker $(pwd)/.build/debug/

Complete the following steps:

1. Import the IBMPushNotifications framework.

   import IBMPushNotifications

Note: For Syndicated use the overrideServerHost param of PushNotifications before initliazong the PushNotifications . Eg: PushNotifications.overrideServerHost = "https://syndicated.region.net"

2. Initialize with details about your IBM Cloud Push Notifications service.

• Initialize with ApiKey

   //Initialize PushNotifications
   let myPushNotifications = PushNotifications(pushApiKey:"your-push-service-apiKey", pushAppGuid: "your-push-service-app_guid", pushRegion: PushNotifications.Region.US_SOUTH)
   
   // GET AUTH TOKEN
   myPushNotifications?.getAuthToken(completionHandler: { (hasToken, tokenString) in
   	if hasToken! {
   		// Send push notifications
   	}
   })

• Initialize with AppSecret

   let myPushNotifications = PushNotifications(pushRegion: PushNotifications.Region.US_SOUTH, pushAppGuid: "your-push-service-guid", pushAppSecret: "your-push-service-appSecret")

3. Create a simple push notification that will broadcast to all devices.

   let messageExample = Notification.Message(alert: "Testing IBMPushNotifications")
   let notificationExample = Notification(message: messageExample)

4. Send the Push notification using the method:

   myPushNotifications.send(notification: notificationExample) { (data, status, error) in
     if error != nil {
       print("Failed to send push notification. Error: \(error!)")
     }
   }

Note: If you are using the APIKEY for Initialisation kindly call getAuthToken() , before sending any notification. This will add an Authorization header for the request.

To create a more selective push notification with specified settings that is only sent to certain devices either by deviceIds or userIds or by device platforms or based on tag-subscriptions, or to set GCM and APNs features - there are optional parameters that you can use in the corresponding initializers.

To send the bulk push notifications of the following,

myPushNotifications.sendBulk(notification: [notificationExample,notificationExample1,notificationExample2]) { (data, status, error) in
	if error != nil {
		print("Failed to send push notification. Error: \(error!)")
	}
}

In Target, you pass the following values:

• deviceIds - Array of device IDs.

• userIds - Array of user IDs.

• platforms - Array of platforms.

• tagNames - Array of tag names.

  let targetExample = Notification.Target(deviceIds: ["device1","device2"],
           userIds: ["userId1", "userId2"],
           platforms: [TargetPlatform.Apple,TargetPlatform.Google,TargetPlatform.ChromeExtApp,
  TargetPlatform.WebChrome,TargetPlatform.webFirefox,TargetPlatform.WebSafari], tagNames: ["tag1", "tag2"])

Note: Do not use userIds, tagNames, platforms and deviceIds together.

Settings can contain any of the following types:

• APNs

• GCM

• FirefoxWeb

• ChromeWeb

• SafariWeb

• ChromeAppExt

  let notificationExample = Notification(message: messageExample,

• titleLocArgs - Variable string values to appear in place of the format specifiers in title-loc-key

• locArgs - Variable string values to appear in place of the format specifiers in locKey.

• title - The title of Rich Push notifications (Supported only on iOS 10 and above)
